Abstract: A mated pair resilient and rigid embossing rolls are disclosed for achieving the advantages of conventional rubber to steel embossing, while avoiding the problems of conventional embossing approaches. In particular, a laser can be utilized to form recesses in a resilient roll such that the resilient roll receives protuberances of a rigid male embossing roll when the rolls are placed in contact. By providing recesses on the resilient roll, the pressure or force required for causing the rubber to flow around the protuberances can be significantly decreased as compared to conventional rubber to steel embossing. As a result, wear on the rolls is reduced, and smaller diameter rolls may be utilized, thereby reducing the cost of the embossing equipment. In addition, since less pressure is required to cause the rubber to flow about the protuberances, roll deflection is not a problem, and an embossed pattern can be imparted having a consistent, high degree of definition across the width of a web.

Abstract: A flat, cloth-like composite laminate including airlaid, nonwoven pulp web layers reinforced by a wetlaid bicomponent web layer. The bicomponent web layer has a sheath-core configuration, wherein the fiber component of the sheath member has a lower melting point than the fiber component of the core member. If desired, an adhesive material can be utilized between the bicomponent layer and the airlaid pulp web layer.

Abstract: Apparatus for dispensing individual sheets from the center of a coreless roll includes a support for supporting the coreless roll which defines an aperture, a dispenser nozzle defining a restricted passageway leading from the aperture, the nozzle having an exit opening, and an insert positioned in the passageway to change the effective size and the configuration of the dispenser nozzle.

Abstract: An article is disclosed comprising a lid engaged to a container by the formation of interlocking waves of lid material and container material at the junction of the lid and container. The interlocking waves are geometrically aligned relative to the interior of the container so as to maximize the burst strength of the container, and also to minimize the force required to peel the lid from the container. An unheated clamp head is used to clamp the lid structure immediately adjacent a heated seal head, the heated seal head being used to form the interlocking wave structure around the inside rim of the container. The clamp head prevents any melted portions of the container or lid from flowing to or towards the outside rim of the container, and thereby prevents the formation of similar interlocking waves about the outside rim of the container.

Abstract: A method for the production of a fibrous web having textile length fibers wherein a fiber furnish is formed by dispersion of the fibers in an unfoamed carrier medium of water and an associative thickener of ethylene oxide base urethane block copolymers or hydroxyethylcellulose ethers having a C.sub.10 to C.sub.24 alkyl side chain in an amount within the range of from about 1 to about 150 pounds of thickener per ton of dry fiber and including an anionic viscosity modifier in the range of 10 to 500 ppm.

Abstract: A system for dispensing individual sheet material segments from a roll of sheet material. The sheet material is separated into individual segments by perforated tear lines which are shaped to incrementally pass through a nip formed by nip rollers due to a pulling force exerted on an end-most segment by a user. A drag force opposed to the pulling force is exerted on the sheet material by the nip rollers so that the tear line tears as it passes through the nip. Tearing along the perforated tear line is not completed until a portion of an adjacent segment is presented for pulling by a subsequent user.
